Icon and Image Sizes

Every app needs an app icon and a launch file or image. In addition, some apps need custom icons to represent app-specific content, functions, or modes in navigation bars, toolbars, and tab bars.

Unlike other custom artwork in your app, the icons and images listed in Table 41-1 must meet specific criteria so that iOS can display them properly. In addition, some icon and image files have naming requirements (to learn about naming these files, see App Icons and App Launch (Default) Images).
